Representatives of the College of Charleston argue those visiting College of Charleston fitness facilities are required to wear a t-shirt. Attire exposing midriff simply isn’t allowed.

That type of attire is why Sarah Villafane says she was thrown out of a student gym. In the public post she made on Facebook Wednesday, she said the attire deemed inappropriate at the gym was also worn to three classes before her workout.

Her argument in the post is she bought the outfit to workout in, so why is it inappropriate?

A spokesman for College of Charleston says there is a sign near the door and those using the gym should be aware of the rule.

Still, some of those aware of the rule and commenting on Villafane’s post argue she should be able to “show curves” if she wants.

College of Charleston spokesman Mike Robertson says the George Street Fitness Center Rules aren’t about controlling attire. In a brief statement sent to ABC News 4, Robertson clarified the rules are in place to reduce skin contact with facility equipment.

“This practice of wearing a t-shirt is for sanitary reasons,” Robertson said. “We want to reduce skin contact with facility equipment. These rules are applied to both males and females.”

Dress Code

1. Athletic attire is to be worn. This includes t-shirts, running shoes, sneakers, shorts, or pants. Footwear must be worn.

2. Clothing or jewelry which compromises the safety of a participant or may possibly damage the equipment is prohibited. Examples include sandals, open-toe shoes, hard-soled shoes, boots, denim jeans, and clothing with metal fasteners.

Robertson said there are similar policies at Winthrop University and Clemson University.
